Product details
Overview
P4KE62HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for robust overvoltage protection of sensitive electronics. It features a 53.0 V stand-off voltage (VWM), 58.9–65.1 V breakdown voltage (VBR) at 1.0 mA test current, 400 W peak pulse power (10/1000 μs), and clamps transients to ≤85.0 V at 4.7 A peak pulse current - deployed on power rails and signal lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the P4KE62HE3/54 datasheet, P4KE62HE3/54 pinout, P4KE62HE3/54 application, or P4KE62HE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, DO-41 mechanical data, clamping performance under standardized surge waveforms, and direct alternatives with documented voltage and power differences.
Technical Context
The P4KE62HE3/54 operates as a unidirectional avalanche diode, leveraging glass-passivated junction technology to achieve fast response (<1 ns) and low incremental surge resistance. Its breakdown mechanism is defined by tightly controlled VBR tolerance (±5% min/max), with thermal derating governed by RθJL = 66 °C/W and TJ(max) = 175 °C.
It is rated for 400 W peak pulse power per 10/1000 μs waveform at 0.01% duty cycle, supports 40 A non-repetitive forward surge (8.3 ms half-sine), and exhibits 1.0 μA max reverse leakage at VWM, enabling reliable protection in high-impedance sensing nodes and 12 V/24 V automotive supply domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 53.0 V - maximum continuous reverse operating voltage before significant leakage; defines safe working margin below breakdown |
| VBR (min/max) | 58.9 V / 65.1 V at 1.0 mA - precise avalanche threshold range ensuring predictable turn-on during transients |
| VC @ IPPM | ≤85.0 V at 4.7 A - clamping voltage limiting downstream component stress during 10/1000 μs surge events |
| PPPM | 400 W - peak transient energy absorption capability under standardized lightning/surge test conditions |
| IFSM | 40 A - single half-sine surge rating (8.3 ms), supporting protection against load dump and inductive kick |
| TJ(max) | 175 °C - maximum junction temperature enabling operation in under-hood automotive environments |
| RθJL | 66 °C/W - thermal resistance from junction to lead, critical for PCB trace heat sinking design |
Pinout & Package
Package: DO-41 (DO-204AL), molded epoxy body with matte tin-plated leads; RoHS-compliant, AEC-Q101 qualified (HE3 suffix); polarity indicated by cathode band on unidirectional devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential side (e.g., GND or return path); conducts during forward surge events |
| Cathode | Avalanche clamping terminal | Connected to protected line (e.g., 12 V rail); initiates breakdown when reverse voltage exceeds VWM |
Key Features

Applications
| Automotive Power Rail Protection | Industrial Sensor Signal Line Protection |
|---|---|
Use Scenario: Protecting 12 V battery-fed microcontroller power inputs in engine control units against load dump and alternator transients. IC Role / Device Role / Timing Role: Unidirectional TVS placed between VIN and GND to clamp surges above 53 V while remaining inert during normal operation. Use Value: Limits peak voltage to ≤85 V during 400 W surges, preventing damage to 5 V LDOs and MCU VDD pins rated for 6 V absolute max. |

IC Role / Device Role / Timing Role: TVS mounted across signal and return paths to suppress EFT bursts and inductive coupling from nearby motor drives. Use Value: Clamps transients within <1 ns while adding only 1.0 μA leakage at 53 V, preserving signal integrity and measurement accuracy. |
| Telecom DC Power Interface | Consumer Device USB Port Protection |
Use Scenario: Shielding 48 V PoE-powered Ethernet switch ports from induced surges due to nearby AC wiring or lightning coupling. IC Role / Device Role / Timing Role: Primary overvoltage clamp on the DC input rail upstream of DC/DC converters and PHY ICs.

Use Scenario: Adding secondary surge protection on VBUS line of USB-C host ports in smart home hubs exposed to user-handled cables. IC Role / Device Role / Timing Role: Back-to-back placement with series impedance to limit let-through energy to downstream USB PD controllers. Use Value: Withstands repeated 10/1000 μs surges up to 4.7 A while meeting UL 94 V-0 flammability for enclosed consumer enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ60A | DO-214AA package; 60 V VWM, 66.7–73.7 V VBR, 600 W PPPM, 100 A IPPM | Higher power rating but larger footprint; better suited for board space-constrained designs requiring >400 W headroom | Select SMBJ60A when higher surge margin is needed and PCB layout allows SMC/SMB package; not drop-in compatible with DO-41 footprints. |
| 1.5KE62A | Same DO-41 package; 53 V VWM, 58.9–65.1 V VBR, but 1500 W PPPM and 24.8 A IPPM | Higher peak power handling; identical pinout and mounting but significantly higher surge current capability | Choose 1.5KE62A for applications subject to severe lightning-induced surges (IEC 61000-4-5 Level 4) where 400 W is insufficient. |
Compared with SMBJ60A and 1.5KE62A, the P4KE62HE3/54 offers AEC-Q101 qualification and optimized thermal resistance (RθJL = 66 °C/W) for automotive under-hood use, whereas SMBJ60A trades qualification for higher power density and 1.5KE62A provides greater surge capacity in the same DO-41 form factor.

FAQ
What is the key difference between P4KE62HE3/54 and P4KE62A-E3/54?
The P4KE62HE3/54 is AEC-Q101 qualified and intended for automotive applications, while the P4KE62A-E3/54 is commercial-grade only. Both share identical electrical specs (VWM = 53.0 V, VBR = 58.9–65.1 V, PPPM = 400 W), but the HE3 variant undergoes additional stress testing per AEC-Q101, including temperature cycling and HTRB, making it suitable for under-hood use. The P4KE62HE3/54 remains the preferred choice where automotive qualification is mandatory.
Does P4KE62HE3/54 support bidirectional transient suppression?
No, the P4KE62HE3/54 is strictly unidirectional - its cathode band marks the terminal that must be connected to the protected line (e.g., +12 V), with anode tied to ground. Bidirectional operation requires a CA-suffixed part like P4KE62CA. Using P4KE62HE3/54 in reverse-biased configurations risks permanent failure, as it lacks symmetrical breakdown characteristics. Always verify polarity during PCB layout and assembly.
What is the maximum clamping voltage of P4KE62HE3/54 under surge conditions?
The P4KE62HE3/54 clamps to a maximum of 85.0 V at its rated peak pulse current of 4.7 A (10/1000 μs waveform). This value is guaranteed per Vishay's datasheet and represents worst-case voltage seen by downstream circuitry during standardized surge events. For design margin, engineers should ensure protected ICs have absolute maximum ratings exceeding 85.0 V, especially when considering tolerances and PCB trace inductance effects.
Is P4KE62HE3/54 compatible with lead-free reflow soldering?
Yes, the P4KE62HE3/54 has matte tin-plated leads qualified per J-STD-002 and JESD 22-B102, and withstands solder dip at 275 °C for up to 10 seconds. It is fully compatible with standard lead-free reflow profiles (peak ~260 °C) and wave soldering. The HE3 suffix also indicates compliance with JESD 201 Class 2 whisker testing, ensuring long-term reliability in high-vibration automotive environments.
How does thermal resistance affect P4KE62HE3/54 performance in high-temperature environments?
The P4KE62HE3/54 has RθJL = 66 °C/W, meaning junction temperature rises 66 °C per watt dissipated in the lead. At elevated ambient temperatures (e.g., 105 °C under hood), power derating becomes critical: its 1.5 W steady-state rating drops significantly above 25 °C, per Fig. 5 in the datasheet. Engineers must size PCB copper pads and traces to act as heatsinks, especially when used in repetitive surge scenarios or high-power industrial settings.
